Apparatus for mounting a sensor

Abstract

The invention relates to an apparatus for aseptic mounting of a sensor ( 1 ), which determines and/or monitors at least one physical and/or chemical process variable relating to a medium ( 3 ) which is located in a container ( 2 ). The invention is based on the object of proposing an apparatus for aseptic mounting of a sensor ( 1 ) on a container ( 2 ). The object is achieved in that a process fitting ( 4 ) is provided, which has an internal area for holding the sensor ( 1 ), with the internal area opening into an opening ( 5 ) on that side of the process fitting which faces the process, and with a shaped seal ( 6 ) being positioned in the opening ( 5 ), which shaped seal ( 6 ) is designed such that, once the sensor ( 1 ) has been fitted, it produces a push fit in the opening ( 5 ) and seals the internal area of the process fitting ( 4 ) from the process without any gap.

1 . An apparatus for aseptic mounting of a sensor ( 1 ), which determines and/or monitors at least one physical and/or chemical process variable relating to a medium ( 3 ) which is located in a container ( 2 ),  
       having a process fitting ( 4 ), which has an internal area for holding the sensor ( 1 ), with the internal area opening into an opening ( 5 ) on that side of the process fitting which faces the process, and with a shaped seal ( 6 ) being positioned in the opening ( 5 ), which shaped seal ( 6 ) is designed such that, once the sensor ( 1 ) has been fitted, it produces a push fit in the opening ( 5 ) and seals the internal area of the process fitting ( 4 ) from the process without any gap.  
     
     
         2 . The apparatus as claimed in  claim 1 ,  
       with the opening ( 5 ) being provided on that end surface ( 13 ) of the process fitting ( 4 ) which faces the process.  
     
     
         3 . The apparatus as claimed in  claim 1 ,  
       with the shaped seal ( 6 ) being essentially annular and having an essentially planar outer surface ( 14 ) toward the process.  
     
     
         4 . The apparatus as claimed in  claim 1  or  3 ,  
       with the shaped seal ( 6 ) having a shoulder ( 16 ) with an essentially planar outer surface ( 14 ) on the side facing away from the process, which outer surface ( 14 ) rests on a corresponding projection ( 15 ) on the inner surface ( 18 ) of the process fitting ( 4 ).  
     
     
         5 . The apparatus as claimed in  claim 1 ,  2 ,  3  or  4 , with the shaped seal ( 6 ) having at least one depression ( 17 ) on its inner surface ( 18 ) facing the sensor ( 1 ).  
     
     
         6 . The apparatus as claimed in  claim 5 ,  
       with the depression ( 17 ) being annular.  
     
     
         7 . The apparatus as claimed in one or more of the preceding claims,  
       with the shaped seal ( 6 ) being composed of silicone, EPDM or FPM.  
     
     
         8 . The apparatus as claimed in  claim 1 ,  
       with a thread ( 9 ) being provided on the sensor, with a corresponding thread ( 10 ) being provided on the inner surface ( 18 ) of the process fitting ( 4 ), and with the sensor ( 1 ) being connected to the process fitting ( 4 ) via the screw connection ( 9 ,  10 ).  
     
     
         9 . The apparatus as claimed in  claim 1  or  8 ,  
       with a mounting part ( 20 ) being provided on the process fitting ( 4 ), via which mounting part ( 20 ) the process fitting ( 4 ) can be mounted, with the sensor ( 1 ), on the container ( 2 ).  
     
     
         10 . The apparatus as claimed in  claim 1 ,  
       with a leakage monitor being provided, which provides information about any leaks through the shaped seal ( 6 ).
